When I'm frustrated by not being able to spend time in my shop, I cruise Ebay for parts. I bought a fuel tank for the Retroblaster-KTM-Bobber-Thing. For $55 shipped, not a bad deal. It's for a CFMoto CF125 Pango (Erroneously referred to on Ebay as "CFMOTO Mandrill"). Not a bolt-up fit by any means, but it'll work.
